Problems solved by technology

In daily maintenance, if the IPC fails and is replaced, the NVR cannot automatically identify the new IPC, and must be manually identified and set again, so the monitoring and management services of some key IPCs will be affected

Embodiment

[0025] The port corresponding method of this NVR and IPC comprises the steps:

[0026] (S10) In a distributed network with NVR as a node, the NVR is connected to multiple IPCs through a switching device, wherein the number of network ports of the switching device is not less than the number of IPCs; wherein, the network ports only refer to Network port for direct or indirect connection to IPC.

[0027] (S20) Explicitly number each network port of the switching device, and bind each numbered network port to different video channels in the NVR; the NVR initializes a corresponding logic for each video channel Interfaces, so that each numbered network port of the switching device is in one-to-one correspondence with the logical interface of the corresponding video channel.

[0028] (S30) Use VLAN isolation and identification for each network port of the switching device to form an independent connection channel from each IPC to the NVR. At the same time, the NVR maintenance inclu...

Abstract

The invention discloses an NVR and IPC port corresponding method comprising the steps that NVRs are connected with multiple IPCs through exchange equipment in a distributed network with the NVRs acting as nodes; explicit numbering is performed on each network port of the exchange equipment, and each numbered network port and different video channels in the NVRs are correspondingly bound in a one-to-one way; and VLAN isolation and identification are performed on each network port of the exchange equipment so as to form an independent connection channel of each IPC to the NVRs, and thus one-to-one correspondence of physical ports and the video channels can be realized. The exchange equipment is ingeniously utilized to provide the actual physical ports, corresponding matching of the logic interfaces of the NVRs is performed with combination of the virtual local area network technology, and a VLAN tag is marked on a transmitted message so that isolation and identification of data transmission can be effectively realized, orderly processing of the NVR ends for multiple receiving video data can be facilitated, and the problems that video data streams are difficult to distinguish in a complex network distribution environment and management is not convenient can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of video network applications, in particular to a port correspondence method between an NVR and an IPC. Background technique [0002] Digital Video Recorder, that is, digital video recorder, compared with traditional analog video recorders, uses hard disk recording, so it is often called hard disk video recorder, also known as DVR. Although it uses digital storage to record video, its front end is still an analog camera, and the transmission method between them is still through analog signal transmission. [0003] With the development of technology, the emergence of NVR (NetworkVideoRecorder, network hard disk recorder) has changed the way of traditional video camera and video recording, making it develop towards the direction of networking. Its main function is to transmit data through IPC (IPCamera, network camera) equipment The digital video stream is stored and managed, so as to realize the advantages o...
